Carl,

Tnx for the reply. Well the idea is quite simple. Since radio
communications don't have the benefit or using wire lines
and are subjectable to all kinds of RF interference, certain
so called, modulation techniques have to be employed in
order to insure "clean" data transfer between two radios.
With this particular modulation scheme you can actually
"twist & turn" the RF signal and distort it to the point of
only couple of dB S/N ratio and still get good data out of
the demodulator, cuz digital 0 and 1 are represented by
pulses of different lengths. But let me get to my question,
as I'm sure the class is anxious to hear it

I need to do couple of other things while I decode the data
i.e. measure pulse widths and that's why I was looking into
CCP module as it can work in the background, undisturbed.
Another thing, if I use the statement:

PULSIN PortB.1,1,Pulse_High
PULSIN PortB.1,0,Pulse_Low

does it mean that PULSIN (high) will wait the timeout
period, before it does the second PULSIN (low) or it just
checks both and does it again (providing I put it in a loop)?

And the last but not the least important. What about the
timings? How fast PULSIN and CCP hardware really are?
Can I precisely measure 200uS with either of these?

Greetings from Novi Sad, Serbia!
